IPC: F04D31/00
Filed: 1995-09-13
Abstract: L'invention concerne un système de pompage pour appliquer à des effluents polyphasiques une pression suffisante pour les transporter depuis une source telle qu'un puits de production pétrolière) jusqu'à un lieu de destination éloigné. Pour améliorer le fonctionnement de la pompe et rendre plus souple la gestion des transferts d'effluents, le système comporte une boucle de recyclage d'une fraction des effluents polyphasiques sortant de la pompe vers l'entrée de celle-ci, comportant de préférence un élément de dérivation tel qu'un T, conformé pour diminuer le rapport volumétrique GLR des effluents recyclés. Dans la boucle est interposé un élément de régulation tel qu'une vanne pilotée et éventuellement un ballon-tampon, et un élément tel qu'un éjecteur mélangeur pour utiliser une partie de l'énergie des effluents dérivés. Application à des installations de pompage offshore par exemple.
Patent CA-2159870-A1 (CA)
Inventor: KHINKIS MARK J
IPC: F23M5/02
Filed: 1995-10-04
Abstract: A porous matrix, surface combustor-fluid heating apparatus in which combustion of a fuel/oxidant mixture is carried out in stages within a stationary porous bed disposed in a combustion chamber.  A fuel-rich fuel/oxidant mixture is burned within a region of the stationary porous bed disposed near the inlet end of the combustion chamber, forming a primary combustion zone.  A secondary oxidant is introduced into the stationary porous bed downstream of the primary combustion zone forming a secondary combustion zone.          Finally, heat resulting from the combustion is removed by fluid flowing through heat exchanger tubes embedded within the stationary porous bed.
Patent CA-2160548-A1 (CA)
Inventor: JOHNSON GARY L
IPC: A61K38/45
Filed: 1994-04-15
Abstract: The isolated nucleic acid sequence for MEKK, the MEKK amino acid sequence and protein, antibodies to MEKK, and methods for using such sequences, proteins and antibodies are described. The amino acid sequence of MEKK (MEK Kinase), was elucidated from a cDNA sequence encoding a protein of 672 amino acid residues (73 kilodaltons). When MEKK is expressed, it phosphorylates and activates MEK. Phosphorylation and activation of MEK by MEKK is independent of Raf, a growth factor regulated protein kinase that also phosphorylates MEK Thus, MEKK and Raf converge at MEK in the protein kinase network mediating the activation of MAPKs by hormones, growth factors, and neurotransmitters.
Patent CA-2160976-A1 (CA)
Title: Direction Indicator Covers for Emergency Lighting Systems
Inventor: SMITH STEPHEN T
IPC: G09F13/04
Filed: 1995-10-19
Abstract: Detachable chevron-shaped panels that fit within chevron-shaped apertures in the cover of an exit sign.  The panels are dimensioned to fit integrally into the apertures in order to withstand years of stress, temperature changes, and wear and tear but continue to perform in a light-fast and reliable manner.  Yet they may be easily installed from the exterior of the exit sign, with minimum risk that they will fall into the interior during installation.  Surprisingly, the present invention permits such easy installation without the need to use conventional "slide 'n' snap" exit sign arrow fasteners that usually allow reliable installation but have proven to be destructive of a secure fit and light fastness.  The panel accomplishes this by employing at least three tabs positioned in a certain manner about the perimeter of each wing of the panel which engage the (preferably bevelled) edge of the chevron-shaped aperture.   The tabs are disposed in various quadrants around the centroid of each wing of the panel in order to create an integral fit of the long chevron wings to the cover and thus to reduce inadvertent detachment of the whole panel if a part of it is dislodged, or if the cover is deformed through heat or physical stress.  Such positioning also provides multiple retention axes between tabs and creates lateral forces and bending moments, should any tab become dislodged, in order to continue securing the wing and the panel in place.

Title: Looper Control System for a Rolling Mill
Inventor: IMANARI HIROYUKI
IPC: B21B37/00
Filed: 1995-11-24
Abstract: A looper control system has a looper that is interposed between two rolling stands of a tandem rolling mill and is actuated by a hydraulic actuator; and a control calculating section for calculating a speed change rate command value of a primary rolling machine and a pressure command value of a hydraulic looper actuator so that an interstand tension and a looper height can be both controlled at target tension and looper height values, respectively, on the basis of a detected looper height value and a previously determined control gain. A resonance frequency changing section detects hydraulic flow rate of the hydraulic actuator and multiplies it by a gain to obtain a first speed change rate command value; and a damping constant changing section detects pressure in the hydraulic actuator and multiplies it by another gain to obtain a second speed change rate command value. The first and second speed change rate command values are added to a speed command value, and the total is set to the primary rolling machine speed controller.
